Hi All,

I have to find a control through Javascript which I have generate dynamically through codebehind.
For ex:

DropDownList ddlCombo = new DropDownList();
ddlCombo.ID = "Combo1";
ddlCombo.CssClass = "text";
ddlCombo.Width = 250;

I need to find the ddlCombo Control in Javascript with it selected index.

How do I do this?? Thanks in advance...

Hi,

you need to find that control on any event or what ?

you can use 2 ways :

1. In code behind itself u can add attribute to control

e.g you can use button click event
btnAdd.Attributes["onclick"] = "javascript:DisableControl('"+ddlCombo.ClientID+"');";
and in javascript
if(document.getElementById(ddvalue).getAttribute("selectedIndex")

or u can directly pass selected index ito javascript

2. in your javascript document.getElementById('Combo1').getAttribute ("selectedIndex") will give u control's index but i m not sure.

Hi Pallavi,

Thanks for the reply but I have done this and it wroks fine. But when I upload my project on server the ID is different and therefore my javascript function doesnt work. Thats is why I need to use .ClientID.

All the controls on my form are generate dynamically. Please help me...

Thanks again...

After adding this DropDownlist to the content i think you can get its client id
Check it

Thanks and Regards

Hey Sandeep, thanks the reply. I am doing something like this :

var Country = $find('<%=ddlCountry.ClientID%>');

but it says

The name 'ddlCountry' does not exist in the current context

Since the control in not available in .acsx as I have created it in code behind.

I hope I am doing right???

Might be ddlCounty is not accessible there as it must be local variable in any method can you post the code related to drop down list ?

Thanks again. Here is the code:
I am adding this DropDownList to tab Container:
DropDownList ddlCountry = new DropDownList();
ddlCountry.ID = "ddlCountry";
ddlCountry.CssClass = "text";
ddlCountry.Width = 250;
tab1.Controls.Add(ddlCountry);

how do I get this ID in Javascript??

Sandeep Akhare5-Nov-07 2:12

Check the id of DDL after adding to tab
like
tab1.Controls.Add(ddlCountry);
ddlCounty.Clientid;
that will give you client id
Now it depends on your code how are you adding this tab to the main content page

Thanks and Regards

Question releted to sql query.

5-Nov-07 2:20

Another way instead of using ASP dropdown list you can use HtmlSelect
Its id will changed runtime
you can give data source and datamember to it

HtmlSelect ddl = new HtmlSelect();
ddl.Items.Add(new ListItem("Sandeep","Sandeep"));

ddl.ID="Sandeep";
PlaceHolder1.Controls.Add(this.Button1);
PlaceHolder1.Controls.Add(ddl);

Thanks and Regards

Hi to all,
I have one query. In my sql auery in am selecting data from two
tables for that purpose i have used join query.I have used follwoing
query.

select distinct blog_new.blgid,blog_new.blogtitle,blog_new.createddate from blog_new,blog_post where blog_new.blgid=blog_post.blgid and blog_new.status=1 order by blog_post.editeddate desc

you are using distinct blgid and join on blgid so even though thr are 3 same blogtitle but if they have diffrent id it will return 3 records

Hi Pallavi,
If they have same blogtitle and same id then it will return only one
row. Is it correct?

Thanks.
Rahul.

Hi Rahul,

if you have same ids how will u get 3 records ..its one record na .. Smile | :)

see in join, u join in which field is matter a lot .. so if u are joining on blogid it must be unique...and so it will have uique ids no matter title same or diffrent.
if u have any query plz ask Smile | :)
